Question

3 years ago, the ratio of Tom's age to Clemmie's age was 2:7

Tom is now 15 years old and Clemmie is now x years old.

Find the value of x.​

Answer 1

To solve this problem, set up an equation using the given information. Solve for x to find the age of Clemmie now.

Step-by-step explanation:

To solve this problem, we can set up an equation using the given information. Let x be the age of Clemmie now. Three years ago, Tom was 15 - 3 = 12 years old. Clemmie was x - 3 years old. The ratio of their ages was 2:7, so we can write the equation:

12/(x - 3) = 2/7

To solve for x, we can cross-multiply:

12 * 7 = 2 * (x - 3)

84 = 2x - 6

2x = 90

x = 45

Therefore, the value of x is 45.
